How to create a square box in which the border of the box will be filled by color depending on the value given on the box?

Just like the above image or an idea or reference to achieve this design, I appreciate the help or suggestion given by community thank you
I have got reference of progress bar which is circular but not able find an approach to solve it.

const boxes = document.querySelectorAll(".box");
const colors = ['red', 'blue', 'green', 'yellow', 'orange', 'violet']
boxes.forEach((box) => {
const insideContent = box.innerText;
box.style.border = `6px solid ${colors[insideContent]}`
})
#app {
display: flex;
}
.box {
width: 50px;
height: 50px;
margin: 10px;
background-color: cyan;
display: flex;
justify-content: center;
align-items: center;
}
<div id="app">
<div class="box">1</div>
<div class="box">2</div>
<div class="box">3</div>
</div>
As per your question I think this is what you are trying to achieve.

First define a pseudo class root
:root {
--color-val: blue;
}
Note: In order to use the --color-val you need to write it as color: var(--color-var) in CSS
Second use JavaScript to update the variable --color-val
let colors =
var root = document.querySelector(':root');
const delay = ms => new Promise(res => setTimeout(res, ms));
const colorChange = async () => {
await delay(1000);
color = colors[Math.floor(Math.random() * colors.length)]
console.log(color)
root.style.setProperty('--color-val', color);
};
colorChange()
Note:
Add the color list you want to select from or go to CodePen for a list of 1000+ hex codes.
Promise are used for asynchronous function and can be skipped by using setTimeOut for a delayed loop or if used with another eventlistener.

I apologize if I misunderstood the question. Wrote in a hurry and without beautyful visualisation, if you disassemble the principle, you can customize it.

Also, instead of the SetInterval script, you can take values from your block width and height styles and output a mathematical calculation in h1 instead of a stopwatch.
upd: After your comment, I decided to do what I wrote about above. You can play with values and math, I add a snippet of another solution that changes the progress bar from the entered values within the entered range. (of course, it would be easier on react than on pure js)
function grade () {
let grade = +document.getElementById("grade").value;
let range = +document.getElementById("range").value;
document.getElementById("timer").innerHTML = `${grade}/${range}`;
progress(grade,range)
}
function progress (value, grade) {
document.getElementById('1').style.backgroundColor = `white`
document.getElementById("left").className = "noactive";
document.getElementById('top').style.width = `0%`
document.getElementById('right').style.height = `0%`

let GradeValuSide = grade/4;
if (value <= GradeValuSide) {

} else if (value > GradeValuSide && value <= (GradeValuSide*2)) {
document.getElementById('top').style.width = `100%`
document.getElementById('right').style.height =

Transition going only one way when removing class

I'm trying to create a sidebar like this:
function show_menu(){
document.querySelector('#sidebar').classList.toggle('sidebar_open');
document.querySelector('#blackscreen').classList.toggle('blackscreen_open');
}
#hamburger {
width: 5rem;
height: 5rem;
background-color: red;
}
#header_wrapper {
display: block;
}
#sidebar {
position: fixed;
top: 0;
right: 0;
width: 0;
height: 100vh;
transition: width 0.25s;
}
.sidebar_open {
width: 50% !important;
background-color: green;
display: grid !important;
}
#blackscreen{
position:fixed;
top:0;
right:0;
width:100vw;
height:100vh;
transition: background-color 0.25s;
}
.blackscreen_open {
background-color: rgba(0, 0, 0, 0.5);
}
<div id="hamburger" onclick="show_menu()">click here</div>
<div id='blackscreen' onclick="show_menu()"></div>
<span id='sidebar'>
</span>
but the sidebar transition only works one way,
My best guess is that the transition requires 2 classes to operate
but since I've removed one class the transition back might not be taking place
so I tried the solution according to this question like this:
function show_menu(){
document.querySelector('#sidebar').classList.toggle('sidebar_open');
document.querySelector('#blackscreen').classList.toggle('blackscreen_open');
}
#hamburger {
width: 5rem;
height: 5rem;
background-color: red;
}
#header_wrapper {
display: block;
}
#sidebar {
position: fixed;
top: 0;
right: 0;
width: 0;
height: 100vh;
}
#sidebar:not(.sidebar_open) {
transition: width 0.25s;
}
.sidebar_open {
width: 50% !important;
background-color: green;
display: grid !important;
}
#blackscreen {
position: fixed;
top: 0;
right: 0;
width: 100vw;
height: 100vh;
transition: background-color 0.25s;
}
.blackscreen_open {
background-color: rgba(0, 0, 0, 0.5);
}
<div id="hamburger" onclick="show_menu()">click here</div>
<div id='blackscreen' onclick="show_menu()"></div>
<span id='sidebar'>
</span>
but as you can see even that didn't work
I'm pretty sure I'm missing something obvious but any & all help is greatly appreciated!

I'm fairly certain that the transition IS working but you're not seeing it because when it's not open, your sidebar doesn't have a background colour, and since you don't have a transition setting for your background attribute, when you remove the sidebar_open class the background colour IMMEDIATELY reverts to none and the width transition becomes invisible.
You should be able to test this by moving background-color: green; from the .sidebar_open class to the #sidebar element.

You need to have the background-color set even when the sidebar is not open. Otherwise, when the class is removed, you can no longer see it even though the width is being animated.
#sidebar {
position: fixed;
top: 0;
right: 0;
width: 0;
height: 100vh;
background-color: green;
transition: width 0.25s;
}
function show_menu() {
document.querySelector('#sidebar').classList.toggle('sidebar_open');
document.querySelector('#blackscreen').classList.toggle('blackscreen_open');
}
#hamburger {
width: 5rem;
height: 5rem;
background-color: red;
}
#header_wrapper {
display: block;
}
#sidebar {
position: fixed;
top: 0;
right: 0;
width: 0;
height: 100vh;
background-color: green;
transition: width 0.25s;
}
.sidebar_open {
width: 50% !important;
display: grid !important;
}
#blackscreen {
position: fixed;
top: 0;
right: 0;
width: 100vw;
height: 100vh;
transition: background-color 0.25s;
}
.blackscreen_open {
background-color: rgba(0, 0, 0, 0.5);
}

addEventListener adds incorrect properties on click - only on 320x480

TL DR it should be display: flex; opacity: 1
I have a menu which works in the following way:
On mouseenter or click, the menu is shown (display: flex, opacity: 1)
On mouseleave or click (outside the menu area) the menu is hidden (display: none, opacity: 0)
The problem occures when I try to "open" the menu in the Dev. Tools on 320x480 resolution.
When I click on the menu area, only #envelope does the transformation. #links (should also transform but don't becouse of the following reasons) which should get display: flex actually gets display: none assigned to it.
Note: It's working in full screen. Something is bothering him with the 320x480 res.
If I can elaborate or provide any additional information, let me know.
Thank you
function hide (){
document.getElementById("links").style.display = "none";
};

document.getElementById("links").style.display = "flex";
document.getElementById("links").style.opacity = "1";

Don't use transition: all because the browser then need to loop through all properties, and it might cause lag.
Don't use position: absolute unless you have to.
I removed #envelope and inserted the "Click here ..." text in a label (explanation why below).
I arranged classes so I didn't have to repeat code.
Pure CSS solution below.
I made a little CSS hack, where I used a label and a checkbox to simulate a click. So when clicking on the label#menu-toggler, the (hidden) checkbox is checked, which triggers #menu-toggler:checked ~ #links.invisible. I had to add another class to #links, otherwise the low specificity wouldn't trigger the change.
html, body { /* new */
margin: 0px;
padding: 0px;
}
#menu {
height: 15vh; /* changed */
background-color: red;
text-align: center;
margin: 0.5rem; /* new */
}
#menu > input#menu-toggler { /* new */
display: none;
}
#menu > .tagline { /* new */
display: block; /* to get padding to work */
padding: 5vh 0px;
transition: opacity 1s;
}
#menu:hover > .tagline { /* new */
opacity: 0;
}
#menu > .tagline, /* new */
#menu > #links /* new */
{
transition-timing-function: ease-out;
}
#menu > #links {
display: flex;
justify-content: space-around; /* changed */

Animating Elements using JS

I am trying to move a div left from its original position i.e. right , the effect that i'm aiming at is that the div goes to left and then slides to the right a bit.
Vanilla JS only.
Code:
CSS:
leftBtn.addEventListener("click", function() {
pushDiv.style.right = "420px";
pushDiv.style.right = "360px";
});
* {
box-sizing: border-box;
font-family: 'Montserrat', sans-serif;
transition: 0.5s ease;
}
.holder{
position: absolute;
left: 50%;
top: 50%;
height: 300px;
width: 800px;
margin: 0 auto;
background: #eee;
transform: translate(-50%, -50%);
box-shadow: 4px 9px 2px #000;
}
.push-div {
width: 350px;
position: absolute;
background: #F44336;
height: 370px;
right: 0;
top: -35px;
border-radius: 5px;
}
<div class="holder">
<button type="button" name="button" id="btn1">Left</button>
<button type="button" name="button" id="btn2">Right</button>
<div class="push-div" id="pushDiv">
</div>
But on clicking on the button it shows 360px rather than giving the effect.
How do I achieve that? I have tried adding a delay but that doesn't seems to work.

var leftBtn = document.getElementById('leftBtn'),
pushDiv = document.getElementById('pushDiv');
leftBtn.addEventListener("click", function() {
pushDiv.style.right = "410px";
setTimeout( function() {
pushDiv.style.right = "360px";
}, 600 );
});
#pushDiv {
position: absolute;
background: red;
top: 100px;
right: 200px;
width: 100px;
height: 100px;
transition: all .6s;
}
<button id="leftBtn">Move It</button>
<div id="pushDiv"></div>

Try using css animations
JS
const pushDiv = document.querySelector('.pushdiv');
leftBtn.addEventListener('click', animate());
function animate(){
pushDiv.addClass('animation');
{
CSS
.animation{
animation: slideleft 0.7s ease-in;
}
#keyframes slideleft{
// enter your animation keyframes there are some cool tutorials that will show you how to do that same effect
}

How to morph a plus sign to a minus sign using CSS transition?

I want to create a toggle button that morphs its shape from a plus sign to a minus sign.
Using CSS only, without the use of pseudo-elements.
My desired effect is to have the vertical line in the "+" sign to shrink into the horizontal line.
I know it's possible but I'm not sure which is the best route to take. I was thinking of doing something with the height but I'm worried about the line-height of browsers changing its position in the element.
$('button').on("click", function(){
$(this).toggleClass('active');
});
button {
color: #ecf0f1;
background: #e74c3c;
width: 50px;
height: 50px;
border: 0;
font-size: 1.5em;
}
button span {
transition: all .75s ease-in-out;
}
button.active span {
/* Code to morph + to - */
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button><span>+</span></button>

Because of the simplicity of the shapes, the easiest way is just to make the + and - with elements. Using pseudo elements would be the cleanest solution, but you can also just use a DOM element and have a slightly messier document structure.
With that in mind, the actual solution is straightforward. We use CSS to position elements to resemble the desired characters, and then "morph" between them by animating that position.
Take a look over the following code, and try to understand what each rule is accomplishing.
button {
color: #ecf0f1;
background: #e74c3c;
width: 50px;
height: 50px;
border: 0;
font-size: 1.5em;
position: relative;
}
button span {
position: absolute;
transition: 300ms;
background: white;
border-radius: 2px;
}
/* Create the "+" shape by positioning the spans absolutely */
button span:first-child {
top: 25%;
bottom: 25%;
width: 10%;
left: 45%;
}
button span:last-child {
left: 25%;
right: 25%;
height: 10%;
top: 45%;
}
/* Morph the shape when the button is hovered over */
button:hover span {
transform: rotate(90deg);
}
button:hover span:last-child {
left: 50%;
right: 50%;
}
<button>
<span></span>
<span></span>
</button>

A (old) jquery Solution:
no need for span, you can do this using text() with a if statement in jquery
$('button').on("click", function() {
$(this).toggleClass('active');
$(this).text() == "+" ? $(this).text("-") : $(this).text("+");
});
button {
color: #ecf0f1;
background: #e74c3c;
width: 50px;
height: 50px;
border: 0;
font-size: 1.5em;
transition: all .75s ease-in-out;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button>+</button>

Ah my bad I've overlooked that OP doesn't want to use any pseudo
elements. But the big advantage with pseudo elements would be that you have less HTML Code and a cleaner structure.
It's also a different morphing animation as OP wants but maybe someone else can use this.
So if you don't mind I'll let my suggestion there.
Maybe something like this?
HTML
<div class="button"></div>
CSS
* {
box-sizing: border-box;
}
html,
body {
height: 100%;
}
body {
margin: 0;
background: #343838;
}
.button {
position: absolute;
width: 55px;
height: 55px;
background: #70975B;
top: 50%;
left: 50%;
transform: translate(-50%, -50%) rotate(0deg);
border-radius: 50%;
cursor: pointer;
z-index: 100;
transition: 0.4s cubic-bezier(0.2, 0.6, 0.3, 1.1);
}
.button:after {
content: '';
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
height: 2px;
width: 50%;
background: white;
}
.button:before {
content: '';
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
height: 50%;
width: 2px;
background: white;
}
.button.clicked {
transform: translate(-50%, -50%) rotate(360deg);
background: #CC2A41;
}
.button.clicked:before {
width: 0;
}
jQuery
$(".button").click(function() {
$(this).toggleClass("clicked");
});
And here a working example
http://codepen.io/svelts/pen/LkyZoZ

try this
$('button').on("click", function() {
var $this = $(this);
$this.toggleClass('toggle');
if ($this.hasClass('toggle')) {
$this.text('+');
} else {
$this.text('-');
}
});
button {
color: #ecf0f1;
background: #e74c3c;
width: 50px;
height: 50px;
border: 0;
font-size: 1.5em;
transition: all .75s ease-in-out;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button class="toggle">+</button>
